Question

I need help solving number 17.

Answer 1

Let x = amount of sales (in dollars)

The salary is $400 and there's an additional 0.06x dollars added on to get to the goal of 790. The equation is therefore

400+0.06x = 790

Let's solve for x

400+0.06x = 790
400+0.06x-400 = 790-400
0.06x = 390
0.06x/0.06 = 390/0.06
x = 6500

The final answer is 6500

This means he must have $6,500 in sales.
